There has been multiple requests from users to change the top icon bar to be able have better visibility. Intuit has listened to this request and gave the user the choice to change the color scheme with the R4 patch. This is how to change your color scheme…
Alternate Icon Bar
In the R4 patch (available via web patch on 12/5/12 and manual patch on 12/12/12), we have introduced an alternative top icon bar with colored icons and a light colored background. This alternate is in response to customer feedback that the black background with white icons is difficult to read.
Customers can choose this option via Edit > Preferences > Desktop View > My Preferences > Switch to colored icons/light background
Colored Differentiator Flags
Customers who manage multiple company files previously used the ‘Color Themes’ feature as a visual indicator to differentiate one file from another. With the R4 patch release (available 12/5/12 via web patch), customers can now identify different company files with a colored flag differentiator. Choose from 14 different flag colors (the same number of ‘Color Themes’ available in earlier versions).
Flags work in the same way as color themes. Customers can choose this option via Edit > Preferences > Desktop View > My Preferences
